Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM ... we can tease out the original audio frequency signal. Simple in theory is often more ...

The more bias current applied to the diodes, the more they will attenuate the main audio signal. The diode bias current is created by a transistor-based peak detector circuit driven off the main ...

And, a true peak program meter displays the peak level of the signal waveform no matter how brief its duration. Enough preamble. It would be great if we start with the proven circuit of a practical ...

It gives audio visual indications when ... This phenomenon is exploited in the circuit to detect the energetic microwave radiations. A pickup coil (L2) with a capacitor (C2) forms the signal detector ...

Moreover, even with a steady and well-defined application schematic, precision of biasing circuit and resistance may impact detection levels ... design for high performance audio applications. He ...

STMicroelectronics has unveiled new class-D automotive audio amplifiers for smart-cockpit applications, engineered for tiny ...

and Signal Processing in May — can detect watermarks added to about two seconds of audio with “almost perfect accuracy,” even when the distance between the speaker and detector is greater ...
